On my main Portal page i've setup an EMAIL link to my helpdesk email address so users can click on it and it opens up a new email with the correct address saying "change this to a summary" etc to make it easier for them to log a call.

Problem is when a user clicks on the link it opens the email but clears the browser window and replaces it with the EMAILTO HTML code.

Scrren shot 2 here shows what happens in IE8 when you click on the live link on the portal page - it opens up the email link in your default email program (in this case oulook) but changes the IE8 window to show the html code that happened in the background.
